Liquid diversion distributor

Abstract

The invention relates to a liquid diversion distributor. The liquid diversion distributor comprises a distribution head and a casing pipe coating the distribution head. A distribution head main body is a hollow circular tube, the lower part of the outer wall of the hollow circular tube is provided with an annular first boss, the first boss is provided with a plurality of opening grooves, the grooves helically extend down to the bottom of the tube wall from the upper edge of the first boss along the first boss and the outer wall of the hollow circular tube and is used for diversion, the casing pipe is a hollow circular tube, the inner wall of the casing pipe corresponding to the first boss is provided with an annular inner boss, the inner diameter of the inner boss fits to the outer diameter of the first boss, the upper end of the casing pipe is connected to the outer wall of the hollow circular tube of the distribution head through spot welding, the lower end of the casing pipe is welded to the outer wall of the hollow circular tube of the distribution head, the grooves are provided with holes for diversion, and the hollow circular tube of the distribution head is coaxial with the longitudinal axis of the casing pipe. According to the liquid diversion distributor, a liquid flows down in a spiral way so that the liquid uniformly flows down and forms a film on the pipe inner wall so that evaporation efficiency is improved, the pipe wall is uniformly heated, the damage rate is reduced and a service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of component manufacturing, and in particular relates to a liquid guide distributor. Background technique [0002] In the prior art, instruments and devices involving liquid diversion, film formation, and heat exchange, including tubular heat exchange devices, evaporators, etc., most of the distribution heads used for liquid diversion have uneven heat dissipation, and the life of the liquid pipeline Short problem; in addition, the distribution head in the existing evaporator is conical, but the conical distribution head cannot be close to the tube wall, resulting in poor film formation of the liquid on the tube wall, low efficiency, and uneven heating of the tube wall. The problem of high damage rate, but there is no related device in the prior art to solve this problem. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a liquid...
